LOG-CHOCK.

Specification of.Letters Patent. Patantefl Sept, 21, 19079.

Application filed March 29, 1909. Serial No. 486,427.

To all whom it may concern:

Be it known that I, TAYLOR H. MAOLAF- :rnxrr'r, a citizen of the UnitedStates, residing at Tenino, in the county of Thurston and State of.Vashingtomhave invented a new and useful Log-Chock, of which thefollowwing is a specification.

This invention relates to log chocks 'employed on logging cars at end of"the bunks for holding the logs at that end, the logs being held at theother end of the bunk by a removable or swinging stake.

It is the object of the present invention to provide a chock of thiskind which is strong and durable, as a ell as simple in structure, andalso to provide for the longitudinal adjustment of the chock on thebunk.

With the foregoing objects in view, the invention consists in a novelconstruction and arrangement of parts to be hereinafter described andclaimed, reference being bad to the drawing hereto annexed in whichligure l is a perspective view of the chock. Fig. 2 is an elevationshowing the application thereof. Fig. 3 is an .end view.

111 the drawing-s5 denotes the supporting member of the chock. Thismember is an I beam, and may be one of the bunks itself, or supportedand secured on top of the bunk. The beam has its web horizontallypresented, and its flanges vertically presented, so that the chock maybe mounted in the channel formed by said parts, and in said flanges is aseries of alined openings 6 which are for a purpose to be presentlydescribed;

The chock comprises a pair of angularly disposed plates? and 8 which areconnected at one of their ends to form an open angular frame having itsangle upwardly presented. 'l. he lower ends of the plates are formedwith eyes 9, and rest upon the web of the beam 5, and their width issuch that they fit between the flanges of the beam. The chock is thusmounted in the channel of the beam, and is thereby prevented from movinglaterally thereon.

Longitudinal movement bf the chock on the beam is prevented by passingbolts 10 through two of the openings 6, and through the eyes 9. Byproviding a series of these bolt holes 6, the chock may be adjustedlongitudinally on the beam. Each bolt has a suitable head on one end,and. a transverse key or cotter pin 11 is passed through a slot in theother end of the bolt, whereby it is readily fastened in place. Uponremoving the bolt 11), the chock may be moved inwardly or outwardly onthe beam 5, thus accommodating it to either wide or narrow loads.

The angle of the plate 8 of the check which faces the logs, is the sameas the angle made by the stake, so as to let the weight come directlydown on the outer plate 7 of the chock. The plate 8 extends at a moreacute angle to the base of the chock than the plate 7, the angle made bythe latter closel approaching a right angle. A strong and rigidstructure is thus had which will successfully resist the strain placedupon it.

hat is claimed is:

1. The combination with a channeled supporting member, of a log chockcomprising an open angular frame seating'in the channel of thesupporting member, and fastening means passing across the supportingmemberthrough the flanges thereof, and engageable with the frame.

2. The combination with a channeled sup.- porting member having aplurality of aliped openings in its flanges, of a log chock comprisingan open angular frame seating in the channel of the supporting member,and said frame having" eyes at its base, and fasteningmeans passingacross the supporting member through the openings in the flangesthereof, and through the eyes of the frame.

In testimony that I claim the foregoing as my own, Ihave hereto affixedmy signature in the presence of two witnesses.
